SPI MicroSD Card Adapter v0.9b for Arduino


CATALEX SD Card Shield Expansion Board - Blue + Black
(Works with Official Arduino Boards and Examples)



















Arduino Examples: SD card datalogger:


Example from Arduino examples shows how to log data from three onboard analog sensors to an SD card using the SD library. 

The circuit:

### SD card attached to SPI bus as follows:

**  GND: Ground
**  VCC: 5v 
**  MOSI - pin 11
**  MISO - pin 12
**  CLK - pin 13
**  CS - pin 4















The log looks like this:

427,407,387
385,385,376
379,377,374
370,370,366
...
...
...
287,288,283
283,284,277
290,291,286
302,301,299
303,300,297

Comma delimited Data was then opened in Libre Office and graph exported to Jpg.
